Thefirst transistor T1 can control that the data voltage Vdata is appliedto the first node N1.

The second transistor T2 can be electrically connected between a secondnode N2 and a third node N3. The second node N2 can be a gate node ofthe driving transistor DRT. The third node N3 can be a drain node or asource node of the driving transistor DRT. The second transistor T2 canbe controlled by a second scan signal Scan2 supplied through a secondgate line GL2. The second transistor T2 can perform an operationcompensating a change of a threshold voltage of the driving transistorDRT.

The third transistor T3 can be electrically connected between a linethat a reference voltage Vref is supplied and the first node N1.

The driving transistor DRT can be electrically connected between afourth node N4 and the third node N3. The first node N4 can beelectrically connected to a line that a first driving voltage VDD issupplied. The first driving voltage VDD, for example, can be ahigh-potential driving voltage. The fourth node N4 can be the sourcenode or the drain node of the driving transistor DRT.

Explaining briefly the driving timing of the subpixel SP illustrated inFIG. 2 , the second scan signal Scan2 of a turned-on level can besupplied through the second gate line GL2. As the transistor disposed onthe subpixel SP is the P type, the turned-on level can be a low level.

The second transistor T2 and the fifth transistor T5 can be turned-on bythe second scan signal Scan2 of the turned-on level.

As the second transistor T2 is turned-on, the second node N2 and thethird node N3 can be electrically connected. A voltage that thethreshold voltage of the driving transistor DRT is reflected to thefirst driving voltage VDD can be applied to the second node N2 throughthe second transistor T2. The change of the threshold voltage of thedriving transistor DRT can be compensated by this process.

It can become a state that a voltage that the threshold voltage of thedriving transistor DRT and the data voltage Vdata are reflected to thefirst driving voltage VDD is applied to the second node N2, and it canbecome a state that the first driving voltage VDD is applied to thefourth node N4. A difference between a voltage of the second node N2 anda voltage of the fourth node N4 can be a voltage that the data voltageVdata and the threshold voltage of the driving transistor DRT arereflected. The driving current corresponding to the data voltage Vdatacan be supplied by the driving transistor DRT.

As the fourth transistor T4 is turned-on, the driving current suppliedby the driving transistor DRT can be supplied to the light-emittingelement ED.

The light-emitting element ED can represent a luminance according to thedriving current, and the subpixel SP including the light-emittingelement ED can display an image corresponding to the image data.

Furthermore, embodiments of the present disclosure can provide afunction of sensing a touch of a user on the display panel 110 byimplementing a touch sensor structure on the display panel 110displaying an image.

FIGS. 3 to 5 are diagrams illustrating examples of a touch sensorstructure included in the touch display device 100 according toembodiments of the present disclosure.

Referring to FIG. 3 , the touch display device 100 can include aplurality of touch electrode lines TEL and a plurality of touch routinglines TL disposed in the display panel 110. The touch display device 100can include a touch driving circuit 150 driving the plurality of touchelectrode lines TEL and the plurality of touch routing lines TL.

Each of the plurality of touch electrode lines TEL can be electricallyconnected to the touch driving circuit 150 through the touch routingline TL. The touch driving circuit 150 can be disposed separately, insome cases, can be disposed to be integrated with a circuit for thedisplay driving. For example, the touch driving circuit 150 can bedisposed in a shape integrated with the data driving circuit 130.

Each of the plurality of touch electrode lines TEL can include aplurality of touch electrodes TE electrically connected to each otheralong one direction. Furthermore, each of the plurality of touchelectrode lines TEL can include a plurality of touch electrodeconnecting patterns CL electrically connecting the plurality of touchelectrodes TE each other.

For example, each of a plurality of X-touch electrode lines X-TEL caninclude a plurality of X-touch electrodes X-TE arranged in a firstdirection and a plurality of X-touch electrode connecting patterns X-CLelectrically connecting the plurality of X-touch electrodes X-TE eachother.

Each of a plurality of Y-touch electrode lines Y-TEL can include aplurality of Y-touch electrodes Y-TE arranged in a second directioncrossing the first direction and a plurality of Y-touch electrodeconnecting patterns Y-CL electrically connecting the plurality ofY-touch electrodes Y-TE each other.

The X-touch electrode line X-TEL and the Y-touch electrode line Y-TELcan be disposed on different layers from each other. Alternatively, theX-touch electrode X-TE and the Y-touch electrode Y-TE can be disposed ona same layer. In this case, one of the X-touch electrode connectingpattern X-CL and the Y-touch electrode connecting pattern Y-CL can bedisposed on a different layer from the touch electrode TE.

The touch electrode TE, for example, can be a tetragonal shape, but notlimited to this.

The touch electrode TE can be made of a transparent conductive material,and can be disposed without interrupting an image display function ofthe display panel 110.

Alternatively, the touch electrode TE can be made of an opaque metal. Inthis case, the touch electrode TE can a shape that an area correspondingto a light-emitting area of the light-emitting element ED disposed inthe display panel 110 is opened. For example, the touch electrode TE isimplemented as a mesh type and disposed to avoid the light-emittingarea.

In a structure that the plurality of X-touch electrode lines X-TEL andthe plurality of Y-touch electrode lines Y-TEL are disposed to crosseach other, the touch driving circuit 150 can drive the touch electrodeline TEL through the touch routing line TL and perform the touchsensing.

For example, one of the X-touch electrode line X-TEL and the Y-touchelectrode line Y-TEL can be a touch driving electrode which a touchdriving signal is applied. The other one of the X-touch electrode lineX-TEL and the Y-touch electrode line Y-TEL can be a touch sensingelectrode which a touch sensing signal is detected.

The touch driving circuit 150 can detect a change of amutual-capacitance generated when a user touches in a state thatdifferent signals are applied to the X-touch electrode line X-TEL andthe Y-touch electrode line Y-TEL.

The touch driving circuit 150 can transmit a sensing data according tothe change of the mutual-capacitance detected to a touch controller. Thetouch controller can detect whether a touch is occurred or not and atouch coordinate on the display panel 110 based on the sensing datareceived from the touch driving circuit 150.

The touch electrode line TEL disposed in the display panel 110 can bedisposed to be divided on a plurality of areas in the active area AA.

As the touch electrode line TEL is disposed to be divided on each area,a load of the touch electrode line TEL can be reduced. In the case thatan area of the display panel 110 increases, the load of the touchelectrode line TEL can be reduced and a performance of the touch sensingcan be improved.

Referring to FIG. 4 , the active area AA of the display panel 110 caninclude a plurality of sub-areas SAA divided by a boundary along thefirst direction and a boundary along the second direction.

The active area AA can include at least two or more sub-areas SAAdivided by a first boundary BL1 along the first direction. The activearea AA can include at least two or more sub-areas SAA divided by asecond boundary BL2 along the second direction.

For example, a first sub-area SAA1 and a second sub-area SAA2 can bedivided e.g., separated) by the first boundary BL1. A third sub-areaSAA3 and the fourth sub-area SAA can be divided (e.g., separated) by thefirst boundary BL1.

The first sub-area SAA1 and the third sub-area SAA3 can be divided(e.g., separated) by the second boundary BL2. The second sub-area SAA2and the fourth sub-area SAA4 can be divided (e.g., separated) by thesecond boundary BL2.

FIG. 4 illustrates an example that the active area AA is divided as foursub-areas SAA, but the active area AA can be divided into a plurality ofsub-areas SAA by the first boundary BL1 and the second boundary BL2.

The touch electrode line TEL disposed on each of the plurality ofsub-areas SAA can be disposed to be separated from the touch electrodeline TEL disposed on a different sub-area SAA.

The touch electrode line TEL disposed on each of the plurality ofsub-areas SAA can be driven independently from each other.

For example, a first X-touch electrode line X-TEL-1 disposed on thefirst sub-area SAA1 can be electrically connected to a first touchdriving circuit 151 through a first X-touch routing line X-TL-1. A firstY-touch electrode line Y-TEL-1 can be electrically connected to thefirst touch driving circuit 151 through a first Y-touch routing lineY-TL-1.

A second X-touch electrode line X-TEL-2 disposed on the second sub-areaSAA2 can be electrically connected to a second touch driving circuit 152through a second X-touch routing line X-TL-2. A second Y-touch electrodeline Y-TEL-2 can be electrically connected to the second touch drivingcircuit 152 through a second Y-touch routing line Y-TL-2.

The first X-touch electrode line X-TEL-1 and the first Y-touch electrodeline Y-TEL-1 can be driven by the first touch driving circuit 151. Thesecond X-touch electrode line X-TEL-2 and the second Y-touch electrodeline Y-TEL-2 can be driven by the second touch driving circuit 152. Thetouch electrode line TEL of the third sub-area SAA3 and the fourthsub-area SAA4 can be disposed as a structure similar to the touchelectrode line TEL disposed on the first sub-area SAA1 and the secondsub-area SAA2, and can be driven as a similar manner.

The touch electrode line TEL disposed on the first sub-area SAA1 and thetouch electrode line TEL disposed on the second sub-area SAA2 areelectrically divided and driven by different touch driving circuits 151and 152 150, the load for the touch sensing can be reduced and theperformance of the touch sensing can be improved.

Furthermore, in some cases, the touch electrode lines TEL disposed ontwo or more sub-areas SAA can be driven by a same touch driving circuit150. For example, the touch electrode line TEL disposed on the firstsub-area SAA1 and the touch electrode line TEL disposed on the secondsub-area SAA2 can be driven by the same touch driving circuit 150. Thetouch electrode line TEL disposed on the third sub-area SAA3 and thetouch electrode line TEL disposed on the fourth sub-area SAA4 can bedriven by the same touch driving circuit 150 that is different from thetouch driving circuit that drives the touch electrode lines TEL in thefirst sub-area SAA1 and the second sub-area SAA2. Alternatively, foranother example, the touch electrode line TEL disposed on the firstsub-area SAA1, the second sub-area SAA2, the third sub-area SAA3 and thefourth sub-area SAA4 can be driven by the same touch driving circuit150. In this case, as the touch electrode line TEL disposed on eachsub-area SAA is disposed as a separated structure, the load of the touchelectrode line TEL can be reduced and the performance of the touchsensing can be improved.

Such as described above, in a structure that the touch electrode lineTEL is disposed separately on each of the plurality of sub-areas SAA,some of the touch routing lines TL can be disposed on the active areaAA.

For example, the first X-touch routing line X-TL-1 electricallyconnected to the first X-touch electrode line X-TEL-1 of the firstsub-area SAA1 and the second X-touch routing line X-TL-2 electricallyconnected to the second X-touch electrode line X-TEL-2 of the secondsub-area SAA2 can be disposed on the non-active area NA.

The second Y-touch routing line Y-TL-2 electrically connected to thesecond Y-touch electrode line Y-TEL-2 of the second sub-area SAA2 can bedisposed on the non-active area NA.

In contrast, a part of the first Y-touch routing line Y-TL-1electrically connected to the first Y-touch electrode line Y-TEL-1 ofthe first sub-area SAA1 can be disposed on the active area AA andanother part of the first Y-touch routing line Y-TL-1 is disposed in thenon-active area NA.

The part of the first Y-touch routing line Y-TL-1 that is disposed inthe active area AA can also be disposed on the second sub-area SAA2. Thefirst Y-touch routing line Y-TL-1 can pass the second sub-area SAA2 andcan be electrically connected to the first Y-touch electrode lineY-TEL-1 disposed on the first sub-area SAA1.

As the part of the first Y-touch routing line Y-TL-1 is disposed on thesecond sub-area SAA2, at least one of the second X-touch electrode lineX-TEL-2 or the second Y-touch electrode line Y-TEL-2 disposed on thesecond sub-area SAA2 can be disposed to be separated on an area wherethe first Y-touch routing line Y-TL-1 is disposed. FIG. 4 illustrates anexample that the second Y-touch electrode line Y-TEL-2 is disposed to bedivided on the second sub-area SAA2 due to an arrangement of the firstY-touch routing line Y-TL-1. As shown in FIG. 4 , each first Y-touchrouting line Y-TL-1 is disposed between a pair of second Y-touchelectrode lines Y-TEL2.

Such as described above, in the case that the touch electrode lines TELare disposed to be divided on each sub-area SAA, the number of the touchrouting line TL connected to the touch electrode line TEL can increase.As the number of the touch routing line TL increases, the non-activearea NA can increase due to an arrangement of the touch routing line TL.But as the first Y-touch routing line Y-TL-1 is electrically connectedto the first Y-touch electrode line Y-TEL-1 of the first sub-area SAA1through the active area AA, it may not be required that a separate areais added for an arrangement of the first Y-touch routing line Y-TL-1 onthe non-active area NA. Without increasing the non-active area NA due toan addition of the first Y-touch routing line Y-TL-1, the touch sensorstructure divided as sub-area SAA can be implemented.

The touch sensor structure divided as the plurality of sub-areas SAA canbe divided as an upper side touch sensor portion (e.g., a first portion)and a lower side touch sensor portion (e.g., a second portion) based onthe first boundary BL1. Furthermore, the touch sensor structure can bedivided as a left side touch sensor portion (e.g., a third portion) anda right side touch sensor portion (e.g., a fourth portion) based on thesecond boundary BL2. Here, the lower side touch sensor portion can bepositioned closer to a pad that the touch routing line TL is connectedto than the upper side touch sensor portion. That is, a distance betweenthe lower touch sensor portion and an area where the pad that the touchrouting line TL is connected is disposed can be less than a distancebetween the upper side touch sensor portion and the area where the padis disposed.

Furthermore, as an area of the second Y-touch electrode line Y-TEL-2 isreduced (e.g., smaller) compared to an area of the first Y-touch routingline Y-TL-1, a sensitivity difference of the touch sensing can beprevented or at least reduced by making an area of the first Y-touchelectrode line Y-TEL-1 identical or similar to an area of the secondY-touch electrode line Y-TEL-2.

Referring to FIG. 5 , at least one first dummy electrode DME1 separatedfrom the first Y-touch electrode line Y-TEL-1 can be disposed on atleast a part of an area of the first sub-area SAA1 corresponding to anarea where the first Y-touch routing line Y-TL-1 is disposed on thesecond sub-area SAA2.

The first dummy electrode DME1 can be electrically separated from thefirst Y-touch electrode line Y-TEL-1.

A width of an area where the first dummy electrode DME1 is disposed canbe identical or similar to a width of the first Y-touch routing lineY-TL-1. Alternatively, the width of the area where the first dummyelectrode DME1 is disposed can be identical or similar to a width of anarea where the second Y-touch electrode line Y-TEL-2 is not disposed onthe second sub-area SAA2. Furthermore, a space between two parts of thefirst Y-touch electrode line Y-TEL-1 disposed on both sides of the firstdummy electrode DME1 can be identical or similar to a space between twoparts of the second Y-touch electrode line Y-TEL-2 disposed on bothsides of the first Y-touch routing line Y-TL-1.

An area of the first Y-touch electrode line Y-TEL-1 disposed on thefirst sub-area SAA1 can be substantially identical to an area of thesecond Y-touch electrode line Y-TEL-2 disposed on the second sub-areaSAA2.

Even the first Y-touch routing line Y-TL-1 is disposed to pass the firstsub-area SAA1, it can be prevented that a difference between touchsensitivity by the first Y-touch electrode line Y-TEL-1 of the firstsub-area SAA1 and touch sensitivity by the second Y-touch electrode lineY-TEL-2 of the second sub-area SAA2 is generated, or the difference canbe reduced.

According to embodiments of the present disclosure, as the active areaAA is divided as the plurality of sub-areas SAA, and the touch is sensedby disposing the touch electrode line TEL on each of the plurality ofsub-areas SAA, thus the load of the touch electrode line TEL can bereduced and the performance of the touch sensing can be improved even anarea of the active area AA increases.

Furthermore, by making an area of the touch electrode line TEL disposedon each sub-area SAA to be identical or similar to each other, thus itcan be prevented that the difference of touch sensitivity by the touchelectrode line TEL disposed on each sub-area SAA is generated.

Each of the plurality of touch electrode TE included in the touchelectrode line TEL, such as an example above-mentioned, can be atetragonal shape, but can have various structures for improving theperformance of the touch sensing.

FIG. 6 is a diagram illustrating an example of a structure of the touchelectrode TE included in the touch sensor structure of the touch displaydevice 100 according to an embodiment of the present disclosure.

Referring to FIG. 6 , it illustrates examples of shapes of the X-touchelectrode X-TE included in the X-touch electrode line X-TEL and theY-touch electrode Y-TE included in the Y-touch electrode line Y-TEL.FIG. 6 is a diagram for describing an example of a structure of thetouch electrode TE, it exemplary illustrates a case that the X-touchelectrode line X-TEL and the Y-touch electrode line Y-TEL are crossingeach other and the X-touch electrode X-TE and the Y-touch electrode Y-TEare disposed on a same layer.

The X-touch electrode X-TE can have a similar shape to the Y-touchelectrode Y-TE.

Describing a shape of the touch electrode X-TE using the X-touchelectrode X-TE as an example, the X-touch electrode X-TE can include atleast a body portion X-TE-a and a plurality of wing portions X-TE-b.

The body portion X-TE-a of the X-touch electrode X-TE can be disposed inthe first direction or the second direction, FIG. 6 illustrates anexample that the body portion X-TE-a of the X-touch electrode X-TE isdisposed in the second direction.

The wing portion X-TE-b of the X-touch electrode X-TE can be disposed ina direction crossing the body portion X-TE-a, FIG. 6 illustrates anexample that the wing portion X-TE-b of the X-touch electrode X-TE isdisposed in the first direction.

A width of the body portion X-TE-a of the X-touch electrode X-TE can beidentical to a width of the wing portion X-TE-b of the X-touch electrodeX-TE. Alternatively, the width of the body portion X-TE-a of the X-touchelectrode X-TE can be greater than the width of the wing portion X-TE-bof the X-touch electrode X-TE.

The body portion X-TE-a of the X-touch electrode X-TE can be disposed tobe alternated with a body portion Y-TE-a of the Y-touch electrode Y-TEin the first direction with a wing portion X-TE-b or a wing portionY-TE-b disposed between the body portion X-TE-a and the body portionY-TE-a.

The wing portion X-TE-b of the X-touch electrode X-TE can be disposed tobe alternated with a wing portion Y-TE-b of the Y-touch electrode Y-TEin the second direction.

The wing portion X-TE-b of the X-touch electrode X-TE and the wingportion Y-TE-b of the Y-touch electrode Y-TE can be disposed to beinterlocked each other. An area that an outer line of the X-touchelectrode X-TE and an outer line of the Y-touch electrode Y-TE are facedto each other can increase. Furthermore, a length of a boundary betweenthe X-touch electrode X-TE and the Y-touch electrode Y-TE can increase.The performance of the touch sensing based on the change of themutual-capacitance between the X-touch electrode X-TE and the Y-touchelectrode Y-TE can be improved.

The X-touch electrode X-TE and the Y-touch electrode Y-TE can bedisposed by using an electrode disposed on a same layer. One of theX-touch electrode X-TE and the Y-touch electrode Y-TE can be connectedby an electrode disposed on a same layer as the touch electrode TE, andthe other can be connected by an electrode disposed on a different layerfrom the touch electrode TE.

For example, the Y-touch electrode Y-TE connected in the seconddirection can be connected by an electrode disposed on a same layer asthe touch electrode TE.

The X-touch electrodes X-TE connected in the first direction can beelectrically connected by the X-touch electrode connecting pattern X-CLdisposed on a different layer from the X-touch electrodes X-TE.

For example, the X-touch electrode X-TE and the Y-touch electrode Y-TEcan be disposed by using a first touch sensor metal TSM1. The X-touchelectrode connecting pattern X-CL can be disposed by using a secondtouch sensor metal TSM2.

The second touch sensor metal TSM2 can be disposed on a different layerfrom the first touch sensor metal TSM1.

The X-touch electrode X-TE and the X-touch electrode connecting patternX-CL can be electrically connected to each other through a contact holeCH.

Such as described above, the touch electrode line TEL can be implementedby using a layer where the first touch sensor metal TSM1 is disposed anda layer where the second touch sensor metal TSM2 is disposed.

By a structure that the touch electrode TE includes the body portionTE-a and the wing portion TE-b, a boundary between the X-touch electrodeX-TE and the Y-touch electrode Y-TE can be increased and sensitivity ofthe touch sensing can be improved. Furthermore, by a structure of thetouch electrode line TEL disposed separately on each sub-area SAA of theactive area AA, the load can be reduced and the performance of the touchsensing can be improved.

FIG. 7 is a diagram illustrating an example that the touch sensorstructure illustrated in FIG. 5 is implemented by the structure of thetouch electrode TE illustrated in FIG. 6 according to an embodiment.FIG. 7 exemplary illustrates a touch sensor structure implemented on anarea indicated by 501 illustrated in FIG. 5 .

Referring to FIGS. 6 and 7 , the active area AA, for example, can bedivided as four sub-areas SAA1, SAA2, SAA3, SAA4 by the first boundaryBL1 and the second boundary BL2. The touch electrode line TEL disposedon each of four sub-areas SAA1, SAA2, SAA3, SAA4 can be disposed to bedivided from each other.

The touch electrode line TEL disposed on each sub-area SAA can includethe plurality of X-touch electrode lines X-TEL and the plurality ofY-touch electrode lines Y-TEL.

Each of the plurality of X-touch electrode lines X-TEL can include theplurality of X-touch electrodes X-TE. Each of the plurality of Y-touchelectrode lines Y-TEL can include the plurality of Y-touch electrodesY-TE. The X-touch electrode X-TE and the Y-touch electrode Y-TE canconstitute one sensing unit SU.

The plurality of X-touch electrodes X-TE included in the X-touchelectrode line X-TEL can be electrically connected by the X-touchelectrode connecting pattern X-CL.

For example, the plurality of X-touch electrode X-TE can be made of thefirst touch sensor metal TSM1. The X-touch electrode connecting patternX-CL can be made of the second touch sensor metal TSM2 disposed on alayer different from a layer where the first touch sensor metal TSM1 isdisposed.

The X-touch electrode connecting pattern X-CL can be disposed in thefirst direction and can be electrically connected to the X-touchelectrode X-TE through the contact hole CH. The plurality of X-touchelectrode X-TE can be electrically connected in the first direction andcan constitute the X-touch electrode line X-TEL.

The X-touch electrode connecting pattern X-CL, for example, can bedisposed on an area overlapping the wing portion X-TE-b of the X-touchelectrode X-TE. The X-touch electrode connecting pattern X-CL may not bedisposed on an area overlapping the wing portion Y-TE-b of the Y-touchelectrode Y-TE. A part of the X-touch electrode connecting pattern X-CLcan overlap the body portion Y-TE-a of the Y-touch electrode Y-TE.

A width Wa1 of the wing portion X-TE-b of the X-touch electrode X-TEpositioned on an area overlapping the X-touch electrode connectingpattern X-CL can be greater than a width Wa2 of the wing portion X-TE-bof the X-touch electrode X-TE positioned on an area not overlapping theX-touch electrode connecting pattern X-CL.

The width Wa1 of the wing portion X-TE-b of the X-touch electrodepositioned on an area overlapping the X-touch electrode connectingpattern X-CL can be greater than a width Wa3 of the wing portion Y-TE-bof the Y-touch electrode Y-TE.

As the X-touch electrode connecting pattern X-CL is disposed to overlapthe wing portion X-TE-b having a large width among the wing portionX-TE-b of the X-touch electrode X-TE, a width of the X-touch electrodeconnecting pattern X-CL or the number of the X-touch electrodeconnecting pattern X-CL can increase. The X-touch electrode X-TE can beelectrically connected while reducing a resistance of the X-touchelectrode connecting pattern X-CL.

On an area where the X-touch electrode connecting pattern X-CL is notdisposed, as a width of the wing portion X-TE-b of the X-touch electrodeX-TE and a width of the wing portion Y-TE-b of the Y-touch electrodeY-TE are small relatively, a structure that a boundary between theX-touch electrode X-TE and the Y-touch electrode Y-TE increases can bemaintained and the performance of the touch sensing can be improved.

The X-touch electrode line X-TEL can be electrically connected to anX-touch electrode contact pad X-CP on a boundary of the active area AAand the non-active area NA.

For example, the X-touch electrode X-TE made of the first touch sensormetal TSM1 can be disposed to be extended to the non-active area NA. TheX-touch electrode contact pad X-CP made of the second touch sensor metalTSM2 can be disposed on an area overlapping the extended X-touchelectrode X-TE. The extended X-touch electrode X-TE and the X-touchelectrode contact pad X-CP can be electrically connected through thecontact hole CH.

Alternatively, the extended portion of the X-touch electrode X-TEdisposed on the non-active area NA and the X-touch electrode contact padX-CP made of the second touch sensor metal TSM2 can be seen as theX-touch electrode contact pad X-CP integrally.

The X-touch electrode contact pad X-CP can be electrically connected tothe X-touch routing line X-TL on the non-active area NA. The X-touchelectrode line X-TEL can be electrically connected to the X-touchrouting line X-TL through the X-touch electrode contact pad X-CP. TheX-touch routing line X-TL can be made of at least one of the first touchsensor metal TSM1 or the second touch sensor metal TSM2.

The plurality of Y-touch electrodes Y-TE included in the Y-touchelectrode line Y-TEL can be directly connected to each other.

For example, the plurality of Y-touch electrodes Y-TE can be made of thefirst touch sensor metal TSM1. The plurality of Y-touch electrodes Y-TEcan be connected in the second direction and can constitute the Y-touchelectrode line Y-TEL.

The Y-touch electrode line Y-TEL disposed on the second sub-area SAA2and the fourth sub-area SAA4 among the plurality of Y-touch electrodelines Y-TEL can be electrically connected to the Y-touch routing lineY-TL disposed on the non-active area NA on the boundary of the activearea AA and the non-active area NA.

For example, the second Y-touch electrode line Y-TEL-2 can beelectrically connected to the second Y-touch routing line Y-TL-2 on theboundary of the active area AA and the non-active area NA. The secondY-touch routing line Y-TL-2 can be made of at least one of the firsttouch sensor metal TSM1 or the second touch sensor metal TSM2.

The Y-touch electrode line Y-TEL disposed on the first sub-area SAA1 andthe third sub-area SAA3 among the plurality of Y-touch electrode linesY-TEL can be electrically connected to the Y-touch routing line Y-TL onthe active area AA.

For example, the first Y-touch electrode line Y-TEL-1 can beelectrically connected to the first Y-touch routing line Y-TL-1 on theactive area AA.

The first Y-touch routing line Y-TL-1 can be disposed on the non-activearea NA and the second sub-area SAA2. The first Y-touch routing lineY-TL-1 can pass the second sub-area SAA2 and can be electricallyconnected to the first Y-touch electrode line Y-TEL-1 disposed on thefirst sub-area SAA1.

The first Y-touch routing line Y-TL-1, for example, can be made of thefirst touch sensor metal TSM1. In some cases, the second touch sensormetal TSM2 can be disposed on an area overlapping the first Y-touchrouting line Y-TL-1 and can be electrically connected to the firstY-touch routing line Y-TL-1 through the contact hole CH, and can reducea resistance of the first Y-touch routing line Y-TL-1.

As the first Y-touch routing line Y-TL-1 is disposed on the secondsub-area SAA2, the second Y-touch electrode line Y-TEL-2 disposed on thesecond sub-area SAA2 can be divided and disposed on both sides of thefirst Y-touch routing line Y-TL-1.

Two parts of the second Y-touch electrode line Y-TEL-2 can beelectrically connected to each other by being connected to the secondY-touch routing line Y-TL-2 on the boundary of the active area AA andthe non-active area NA.

Furthermore, the two parts of the second Y-touch electrode line Y-TEL-2can be electrically connected to each other by a second Y-touchelectrode connecting pattern Y-CL-2 disposed on the active area AA.

The second Y-touch electrode connecting pattern Y-CL-2, for example, canbe made of the second touch sensor metal TSM2.

The two parts of the second Y-touch electrode line Y-TEL-2 can beelectrically connected to each other by at least one second Y-touchelectrode connecting pattern Y-CL-2. For example, the second Y-touchelectrode connecting pattern Y-CL-2 can be disposed on an area adjacentto an upper boundary of the sensing unit SU and an area adjacent to alower boundary of the sensing unit SU, and can be electrically connectedto the second Y-touch electrode line Y-TEL-2.

As the two parts of the second Y-touch electrode line Y-TEL-2 disposedto be separated from each other are connected on a plurality of pointsby the second Y-touch electrode connecting pattern Y-CL-2, it can beprevented that the load increases by a structure that the second Y-touchelectrode line Y-TEL-2 is divided.

The first Y-touch routing line Y-TL-1 can pass the second sub-area SAA2and can be electrically connected to the first Y-touch electrode lineY-TEL-1 on the first sub-area SAA1.

As the first Y-touch routing line Y-TL-1 passes the second sub-area SAA2and is extended to the first sub-area SAA1, a portion of the firstY-touch routing line Y-TL-1 can be disposed on the first boundary BL1.

A point that the first Y-touch routing line Y-TL-1 is connected to thefirst Y-touch electrode line Y-TEL-1 can be positioned inside of thefirst sub-area SAA1. The point that the first Y-touch routing lineY-TL-1 is connected to the first Y-touch electrode line Y-TEL-1 may notbe positioned on the boundary of the first sub-area SAA1 and the secondsub-area SAA2.

As the first Y-touch routing line Y-TL-1 passes the second sub-area SAA2and is electrically connected to the first Y-touch electrode lineY-TEL-1 disposed on the first sub-area SAA1, in a structure that thetouch electrode line TEL is divided and disposed on the plurality ofsub-areas SAA, the touch routing line TL can be disposed withoutincreasing the non-active area NA.

Since an area of the second Y-touch electrode line Y-TEL-2 decreasesaccording to that the first Y-touch routing line Y-TL-1 is disposed onthe second sub-area SAA2, an area of the first Y-touch electrode lineY-TEL-1 positioned on an area corresponding to the second Y-touchelectrode line Y-TEL-2 can be identical or similar to an area of thesecond Y-touch electrode line Y-TEL-2.

For example, the first Y-touch electrode line Y-TEL-1 can be disposed tobe divided as two parts similar to the second Y-touch electrode lineY-TEL-2.

The two parts of the first Y-touch electrode line Y-TEL-1 can beelectrically connected to each other by a first Y-touch electrodeconnecting pattern Y-CL-1. A load increase due to a structure that thefirst Y-touch electrode line Y-TEL-1 is divided can be prevented by thefirst Y-touch electrode connecting pattern Y-CL-1.

At least one first dummy electrode DME1 can be disposed between the twoparts of the first Y-touch electrode line Y-TEL-1.

The first dummy electrode DME1 can be disposed to be electricallyseparated from the first Y-touch electrode line Y-TEL-1 and the firstY-touch routing line Y-TL-1.

A boundary of the first dummy electrode DME1 and the first Y-touchrouting line Y-TL-1 can be different from the boundary of the firstsub-area SAA1 and the second sub-area SAA2. The boundary of the firstdummy electrode DME1 and the first Y-touch routing line Y-TL-1 can bepositioned inside of the first sub-area SAA1.

The first dummy electrode DME1 can be disposed on the first sub-areaSAA1 to be corresponded to a portion of the first Y-touch routing lineY-TL-1 disposed on the second sub-area SAA2. A width of the first dummyelectrode DME1 can be identical or similar to a width of the firstY-touch routing line Y-TL-1.

An area of the first Y-touch electrode line Y-TEL-1 disposed on thefirst sub-area SAA1 can be reduced to be corresponding to that an areaof the second Y-touch electrode line Y-TEL-2 is reduced due to anarrangement of the first Y-touch routing line Y-TL-1 on the secondsub-area SAA2. An electrode positioned on an area remained according todecreasing an area of the first Y-touch electrode line Y-TEL-1 canbecome the first dummy electrode DME1.

While maintaining touch sensitivity by the touch electrode line TELdisposed on the first sub-area SAA1 and touch sensitivity by the touchelectrode line TEL disposed on the second sub-area SAA2 to be identicalor similar to each other, a structure that some of the touch routinglines TL is disposed on the active area AA can be implemented.

As the Y-touch routing line Y-TL is disposed in the second direction, aportion of the Y-touch routing line Y-TL can be positioned on the firstboundary BL1.

As the second boundary BL2 which is a boundary of the second directiondivides the first sub-area SAA1 and the third sub-area SAA3, the secondsub-area SAA2 and the fourth sub-area SAA4, the Y-touch routing lineY-TL disposed in the second direction may not be disposed on the secondboundary BL2.

The first Y-touch routing line Y-TL-1 can be extended from the boundaryof the active area AA and the non-active area NA to the non-active areaNA and can cross the second Y-touch routing line Y-TL-2. On an areawhere the first Y-touch routing line Y-TL-1 and the second Y-touchrouting line Y-TL-2 are crossing each other, both can be disposed ondifferent layers.

Such as described above, according to embodiments of the presentdisclosure, the touch sensor structure being capable of reducing theload by the touch electrode line TEL can be provided by a structure thatthe touch electrode line TEL is divided and disposed on the plurality ofsub-areas SAA. Furthermore, as a portion of the touch routing line TL isdisposed on the active area AA, a structure being capable of improvingthe performance of the touch sensing can be provided without thenon-active area NA due to an arrangement of the touch routing line TL.

The touch electrode TE constituting the touch electrode line TEL, suchas an example above-mentioned, can be made of the transparent conductivematerial, or can be made of the opaque metal material. In the case thatthe touch electrode TE is the opaque metal material, the touch electrodeTE can have a shape that an area corresponding to the light-emittingarea of the subpixel SP is opened for not dropping the image displayperformance of the display panel 110. The shape of the touch electrodeTE including the opened portion can be various according to types of thesubpixel SP.

Furthermore, a structure ofthe touch routing line TL electrically connected to the touch electrodeTE can be identical to a structure of the electrode illustrated in FIG.8 .

Referring to FIG. 8 , it exemplary illustrates a structure that adisplay signal line DSL supplying a signal for the display driving isdisposed on the display panel 110 and the touch electrode TE isdisposed.

The display signal line DSL can be include a plurality of first displaysignal lines DSL1 disposed in the first direction and a plurality ofsecond display signal lines DSL2 disposed in the second direction.

The first display signal line DSL1, for example, can be the gate line GLor the light-emitting control line EML.

The first portion TE_f, the second portion TE_s and the third portionTE_t of the touch electrode TE can be disposed to avoid thelight-emitting area of the subpixel SP.

The touch electrode TE can be disposed between the light-emitting areasof adjacent subpixels SP and can prevent or reduce that the touchelectrode TE affects the image displaying according to a viewing angle.

As the touch electrode TE is disposed to avoid the light-emitting areaof the subpixel SP, thus the touch electrode TE can be disposed tooverlap a certain structure positioned on the subpixel SP.

For example, the first portion TE_f of the touch electrode TE disposedin the first direction can be disposed to overlap at least a portion ofthe contact hole CH for an electrical connection between the firstelectrode E1 of the light-emitting element ED and a thin film transistorTFT on the subpixel SP.

The light-emitting layer EL and the second electrode E2 of thelight-emitting element ED can be disposed on a portion of the firstelectrode E1 exposed by the bank BNK and the bank BNK. The portion ofthe first electrode E1 exposed by the bank BNK can correspond to thelight-emitting area.

An encapsulation layer ENCAP can be disposed on the second electrode E2of the light-emitting element ED. The encapsulation layer ENCAP caninclude a plurality of layers. The encapsulation layer ENCAP can includeat least one inorganic layer and at least one organic layer.

For example, the encapsulation layer ENCAP can include a first inorganicencapsulation layer PAS1, an organic encapsulation layer PCL and asecond inorganic encapsulation layer PAS2.

The inorganic encapsulation layer PAS1, PAS2, for example, can be madeof an inorganic insulating material such as silicon nitride SiNx,silicon oxide SiOx, silicon oxynitride SiON or aluminum oxide Al2O3,which can be deposited at a low temperature. The organic encapsulationlayer PCL, for example, can be made of an organic insulating materialsuch as an acrylic resin, an epoxy resin, polyimide, polyethylene orsilicon oxycarbon SiOC.

The encapsulation layer ENCAP can seal the light-emitting element ED andcan protect the light-emitting element ED from an external moisture andair.

The touch sensor structure for the touch sensing can be implemented onthe encapsulation layer ENCAP.

For example, a touch buffer layer TBUF can be disposed on theencapsulation layer ENCAP. The touch buffer layer TBUF can be aninorganic layer. In some cases, the touch buffer layer TBUF may not bedisposed, but the touch buffer layer TBUF can be disposed for making iteasy to arrange the touch sensor metal TSM on the encapsulation layerENCAP.

A touch insulating layer TILD can be disposed on the touch buffer layerTBUF.

Even though FIG. 10 does not illustrate the second touch sensor metalTSM2, but the second touch sensor metal TSM2 constituting the touchelectrode connecting pattern CL or the like can be disposed between thetouch buffer layer TBUF and the touch insulating layer TILD.

The touch insulating layer TILD can be an inorganic layer.Alternatively, the touch insulating layer TILD can be an organic layer.

In the case that the touch insulating layer TILD is an organic layer, athickness of the touch insulating layer TILD can be greater than athickness of the touch buffer layer TBUF.

Furthermore, in the case that the touch insulating layer TILD is anorganic layer, such as <EX 2> of FIG. 10 , a touch insulating bufferlayer TIBUF can be further disposed between the touch insulating layerTILD and the touch buffer layer TBUF. Such as described above, two ormore buffer layer can be disposed between the encapsulation layer ENCAPand the touch insulating layer TILD.

The touch insulating buffer layer TIBUF can be disposed between thetouch insulating layer TILD and the second touch sensor metal TSM2. Thetouch insulating buffer layer TIBUF can be an inorganic layer. The touchinsulating buffer layer TIBUF can be made of a same material as thetouch buffer layer TBUF.

At least a portion of the touch insulating layer TILD can be disposed tocontact a top surface of the touch insulating buffer layer TIBUF.

As the touch insulating buffer layer TIBUF made of an inorganic layer isdisposed between the touch insulating layer TILD and the second touchsensor metal TSM2, an adhesion of the touch insulating layer TILD whichis an organic layer can become easier.

A thickness of the touch insulating buffer layer TIBUF can be smallerthan a thickness of the touch insulating layer TILD, and can be similarto a thickness of the touch buffer layer TBUF.

The touch electrode TE can be disposed on the touch insulating layerTILD. The first touch sensor metal TSM1 can be disposed on the touchinsulating layer TILD and can constitute the touch electrode TE.Furthermore, the first touch sensor metal TSM1 can be disposed on thetouch insulating layer TILD and can constitute the touch routing lineTL.

FIG. 10 exemplary illustrates a cross-sectional structure of a portionthat the first portion TE_f of the touch electrode TE illustrated inFIG. 9 is disposed. The first portion TE_f of the touch electrode TE canbe disposed on the touch insulating layer TILD.

The first portion TE_f of the touch electrode TE can be disposed toavoid the light-emitting area of the light-emitting element ED. Thus,the first portion TE_f of the touch electrode TE is non-overlapping withthe light-emitting area. The first portion TE_f of the touch electrodeTE can be disposed on an area overlapping at least a portion of thecontact hole CH for an electrical connection between the first electrodeE1 of the light-emitting element ED and the thin film transistor TFT.

The first portion TE_f of the touch electrode TE can be disposed betweenadjacent display signal lines DSL disposed in the first direction, orcan be disposed to overlap a portion of the display signal line DSL.

As the touch electrode TE is positioned on an area overlapping thecontact hole CH and is disposed to avoid the light-emitting area of thelight-emitting element ED, the touch sensor structure can be implementedwithout dropping the image display function of the display panel 110.

A touch protective layer TPAS can be disposed on the touch electrode TEmade of the first touch sensor metal TSM1 and can protect the touchelectrode TE.

Such as described above, as each portion of an electrode constitutingthe touch electrode TE or the touch routing line TL is disposed on anarea not overlapping the light-emitting area of the light-emittingelement ED disposed on the subpixel SP and is disposed on a positionreducing an interruption of a viewing angle of the light-emitting area,thus the touch sensor structure can be implemented while preventing orreducing reduction of image display performance of the display panel110.

Below, a specific example that the touch sensor structure illustrated inFIG. 5 is implemented by the touch electrode TE and the touch routingline TL having an electrode structure above-mentioned will be described.Furthermore, such as described above, the touch electrode TE can havevarious shapes other than an electrode structure above-mentioned, andembodiments of the present disclosure can be applied to variouselectrode structures.

FIGS. 11 to 13 are diagrams illustrating specific examples that a touchsensor structure of the touch display device 100 is implemented on theactive area AA of the display panel 110 according to embodiments of thepresent disclosure.

FIG. 11 illustrates an example of a structure of the touch electrode TEdisposed on an area where the sub-areas SAA are divided on the activearea AA according to an embodiment. FIG. 12 illustrates an example of astructure of the touch routing line TL and the dummy electrode DMEdisposed on the active area AA according to an embodiment. FIG. 13illustrates an example of a boundary of the touch routing line TL andthe dummy electrode DME on the active area AA according to anembodiment.

Referring to FIG. 11 , the active area AA of the display panel 110 canbe divided as the plurality of sub-areas SAA by the first boundary BL1and the second boundary BL2. The touch electrode line TEL disposed oneach of the plurality of sub-areas SAA can be disposed to be separatedfrom each other. A schematic diagram illustrating an overall structureof the display panel 110 in FIG. 11 illustrates portions made of thefirst touch sensor metal TSM1 for a convenience of an illustration.

Some of the touch electrode lines TEL disposed on the plurality ofsub-areas SAA can be electrically connected to the touch routing line TLdisposed on the non-active area NA on the boundary of the active area AAand the non-active area NA.

Other some of the touch electrode lines TEL disposed on the plurality ofsub-areas SAA can be electrically connected to the touch routing line TLdisposed to pass the active area AA from the non-active area NA on theactive area AA.

The touch electrode TE constituting the touch electrode line TEL caninclude at least one body portion TE-a and the plurality of wingportions TE-b.

The touch electrode line TEL and the touch routing line TL can beimplemented by cutting an electrode including the first portion TE_f,the second portion TE_s and the third portion TE_t in a certaindirection.

For example, an electrode can be cut on a boundary of the X-touchelectrode line X-TEL and the Y-touch electrode line Y-TEL. The electrodecan be cut on a boundary of the touch routing line TL, the dummyelectrode DME and the touch electrode line TEL. Furthermore, theelectrode can be cut on a boundary of the sub-area SAA.

Referring to FIG. 11 , an electrode can be cut in the first direction onthe first boundary BL1. The electrode can be cut in the second directionon the second boundary BL2.

By cutting the electrode on the first boundary BL1 and the secondboundary BL2, the touch electrode line TEL disposed on each of the firstsub-area SAA1, the second sub-area SAA2, the third sub-area SAA3 and thefourth sub-area SAA4 can be divided.

The X-touch electrode line X-TEL and the Y-touch electrode line Y-TELdisposed on each sub-area SAA can be implemented by cutting theelectrode in the first direction or the second direction.

A space between the touch electrodes TE on the boundary of the sub-areaSAA can be identical or similar to a space between the touch electrodesTE inside of the sub-area SAA. As a space between electrodes cut issubstantially identical, a difference of visibility may not be generatedaccording to regions of the display panel 110.

The touch routing line TL and the dummy electrode DME can be implementedby cutting an electrode as a similar method to the touch electrode lineTEL.

Referring to FIG. 12 , a portion indicated by 1201 illustrates anexample of an area where the first dummy electrode DME1 is disposed onthe first sub-area SAA1. A portion indicated by 1202 illustrates anexample of an area where the first Y-touch routing line Y-TL-1 isdisposed on the second sub-area SAA2.

The first Y-touch routing line Y-TL-1 can be disposed by cutting anelectrode disposed on the second sub-area SAA2.

The first Y-touch routing line Y-TL-1 can be positioned between twoparts of the second Y-touch electrode line Y-TEL-2 on the secondsub-area SAA2.

At least one first dummy electrode DME1 can be disposed by cutting anelectrode disposed on the first sub-area SAA1. The at least one firstdummy electrode DME1 can be positioned on an area corresponding to anarea where the first Y-touch routing line Y-TL-1 is disposed on thesecond sub-area SAA2 in the first sub-area SAA1.

The first dummy electrode DME1 can be positioned between the firstY-touch electrode line Y-TEL-1 on the first sub-area SAA1. The pluralityof first dummy electrodes DME1 can be separated from each other and canbe disposed such as an example illustrated in FIG. 12 so that a defectis not occurred even if a portion of the first dummy electrode DME1 isshorted.

The first dummy electrode DME1 electrically separated from the firstY-touch electrode line Y-TEL-1 can be positioned between the firstY-touch electrode line Y-TEL-1 of the first sub-area SAA1. The firstY-touch routing line Y-TL-1 electrically separated from the secondY-touch electrode line Y-TEL-2 can be positioned between the secondY-touch electrode line Y-TEL-2 of the second sub-area SAA2.

The first dummy electrode DME1 and the first Y-touch routing line Y-TL-1can be disposed to be corresponded to each other. A width of an areawhere the first dummy electrode DME1 is disposed can be identical orsimilar to a width of an area where the first Y-touch routing lineY-TL-1 is disposed. That is, the lower side touch sensor portion caninclude an area where the first Y-touch routing line Y-TL-1 of the upperside touch sensor portion passes, and in the upper side touch sensorportion, the first dummy electrode DME1 can be provided on an areacorresponding to the first Y-touch routing line Y-TL-1 disposed on thelower side touch sensor portion.

At least one second dummy electrode DME2 can be disposed by cutting anelectrode portion between the first Y-touch routing line Y-TL-1 and thesecond Y-touch electrode line Y-TEL-2 on the second sub-area SAA2.

The second dummy electrode DME2 can be disposed to be electricallyseparated from the first Y-touch routing line Y-TL-1 and the secondY-touch electrode line Y-TEL-2.

The first dummy electrode DME1 can be positioned on a portion of thefirst sub-area SAA1 corresponding an area where the second dummyelectrode DME2 is disposed on the second sub-area SAA2. Some of thefirst dummy electrodes DME1 can be disposed to be corresponded to thesecond dummy electrode DME2.

The second dummy electrode DME2 can be disposed to prevent or reduce adrop of visibility due to an arrangement of the touch electrode lineTEL. Alternatively, the second dummy electrode DME2 can be disposed toprevent a short circuit between the first Y-touch routing line Y-TL-1and the second Y-touch electrode line Y-TEL-2.

The first dummy electrode DME1 can be disposed, or the first Y-touchrouting line Y-TL-1 and the second dummy electrode DME2 can be disposedon an area corresponding to each other on the first sub-area SAA1 andthe second sub-area SAA2. An area of the area where the Y-touchelectrode line Y-TEL is disposed on each of the first sub-area SAA1 andthe second sub-area SAA2 can be identical or similar. A space betweentwo parts of the first Y-touch electrode line Y-TEL-1 disposedseparately on both sides of the first dummy electrode DME1 on the firstsub-area SAA1 can be identical or similar to a space between two partsof the second Y-touch electrode line Y-TEL-2 disposed separately on bothsides of the first Y-touch routing line Y-TL-1 on the second sub-areaSAA2.

The first dummy electrode DME1 and the second dummy electrode DME2 canbe disposed by cutting an electrode similarly with the touch electrodeline TEL or the touch routing line TL. The dummy electrode DME can bedisposed by cutting an electrode in the first direction or the seconddirection similarly with the touch electrode line TEL or the like.

Alternatively, at least one of the first dummy electrode DME1 or thesecond dummy electrode DME2 can be disposed to be cut in differentdirection from a direction that the touch electrode line TEL and thetouch routing line TL are cut.

For example, the touch electrode line TEL and the touch routing line TL,such as described above, can be disposed by cutting an electrode in thefirst direction or the second direction. Whereas, the first dummyelectrode DME1 and the second dummy electrode DME2 can be disposed bycutting an electrode in a direction other than the first direction andthe second direction. Both sides (ends) of each of the first dummyelectrode DME1 and the second dummy electrode DME2 can be a shape cut inthe third direction different from the first direction and the seconddirection.

For example, the dummy electrode DME can be disposed by cutting anelectrode in a diagonal direction on a boundary of the dummy electrodeDME and the touch electrode line TEL or the touch routing line TL. Bothsides of the dummy electrode DME can be a shape cut in the diagonaldirection. In the case that a boundary of the dummy electrode DME is ashape cut in the diagonal direction, an area of an end portion of thedummy electrode DME can be greater than an area of an end portion of thetouch electrode line TEL or an end portion of the touch routing line TL.

A boundary between the touch electrode line TEL and the touch electrodeline TEL, a boundary between the touch electrode line TEL and the touchrouting line TL can be shapes that an electrode is cut in the firstdirection or the second direction.

A boundary between the dummy electrode DME and the touch electrode lineTEL, a boundary between the dummy electrode DME and the touch routingline TL, and a boundary between the dummy electrodes DME can be shapescut in the third direction (e.g., the diagonal direction) different fromthe first direction and the second direction.

The dummy electrode DME can have a shape that an electrode is cut in thediagonal direction on a boundary of the dummy electrode DME. The touchelectrode line TEL or the touch routing line TL can include a protrusionwhich protrudes toward the dummy electrode DME and has a shape cut inthe diagonal direction on a boundary of the dummy electrode DME and thetouch electrode line TEL or the touch routing line TL.

As a cutting direction of a boundary of the dummy electrode DME isdifferent from a cutting direction of a boundary of the touch electrodeline TEL or the touch routing line TL, a repair process can be easier inan inspection process of the touch sensor structure.

For example, in the case that a shorted portion between electrodes ispresent on a boundary that electrodes are cut in the first direction orthe second direction, the repair process to cut the shorted portion isnecessary since the corresponding area is a boundary between the touchelectrode lines TEL or a boundary between the touch electrode line TELand the touch routing line TL.

In the case that a shorted portion between electrodes is present on aboundary that the electrodes are cut in the diagonal direction, as atleast one of the shorted electrodes is the dummy electrode DME, it maynot affect the touch sensor structure even if the shorted portion is notcut. Thus, the inspection process can be terminated without the repairprocess. In this case, the dummy electrode DME can be disposed as astructure that the dummy electrode DME is connected to the touchelectrode line TEL or the touch routing line TL on the active area AA.

Such as described above, by the arrangement of the dummy electrode DME,an area of the touch electrode line TEL can be uniform, and visibilitycan be improved. Furthermore, as a cutting direction on a boundary ofthe dummy electrode DME is different from a cutting direction on aboundary of the touch electrode line TEL or the like, an efficiency ofthe inspection process can be increased.

Although examples above-mentioned describe cases that the dummyelectrode DME is disposed on an area corresponding to the touch routingline TL or a periphery of the touch routing line TL only, in some cases,the dummy electrode DME can be disposed inside of the touch electrodeline TEL or a boundary area between the touch electrode lines TEL. Inthis case, the dummy electrode DME can be positioned uniformly on eacharea.

A boundary between the first dummy electrode DME1 disposed on the firstsub-area SAA1 and the first Y-touch routing line Y-TL-1 electricallyconnected to the first Y-touch electrode line Y-TEL-1 of the firstsub-area SAA1 can be cut in a similar manner.

Referring to FIG. 13 , a portion indicated by 1301 represents a boundarybetween the first Y-touch routing line Y-TL-1 and the first dummyelectrode DME1.

A boundary between the first Y-touch routing line Y-TL-1 and the firstdummy electrode DME1 can be a shape that an electrode is cut in thediagonal direction.

Alternatively, in some cases, a boundary between the first Y-touchrouting line Y-TL-1 and the first dummy electrode DME1 can be a shapecut in the first direction. As a plurality of first dummy electrodesDME1 are disposed to be separated from each other, only a boundary ofthe first dummy electrode DME1 which is the most adjacent to the firstY-touch routing line Y-TL-1 may not be a shape cut in the diagonaldirection.

As the first Y-touch routing line Y-TL-1 is electrically connected tothe first Y-touch electrode line Y-TEL-1 disposed on the first sub-areaSAA1, a boundary between the first Y-touch routing line Y-TL-1 and thefirst dummy electrode DME1 can be different from a boundary between thefirst sub-area SAA1 and the second sub-area SAA2. For example, theboundary between the first Y-touch routing line Y-TL-1 and the firstdummy electrode DME1 can be positioned inside of the first sub-areaSAA1.

The first Y-touch routing line Y-TL-1 can be directly connected to thefirst Y-touch electrode line Y-TEL-1 inside of the first sub-area SAA1.The first Y-touch routing line Y-TL-1 and the first Y-touch electrodeline Y-TEL-1 can be directly connected to each other since both of themare made of the first touch sensor metal TSM1.

Alternatively, the first Y-touch routing line Y-TL-1 can be electricallyconnected to the first Y-touch electrode line Y-TEL-1 by the firstY-touch electrode connecting pattern Y-CL-1 made of the second touchsensor metal TSM2.

The first Y-touch routing line Y-TL-1 and the first Y-touch electrodeline Y-TEL-1 can be electrically connected to each other by the firstY-touch electrode connecting pattern Y-CL-1 positioned on an upper sideof the first boundary BL1. Two parts of the second Y-touch electrodeline Y-TEL-2 disposed on the second sub-area SAA2 can be electricallyconnected to each other by the second Y-touch electrode connectingpattern Y-CL-2 positioned on a lower side of the first boundary BL1.

In the case that the first Y-touch routing line Y-TL-1 and the firstY-touch electrode line Y-TEL-1 are connected by the first Y-touchelectrode connecting pattern Y-CL-1, the first Y-touch routing lienY-TL-a and the first Y-touch electrode line Y-TEL-1 can be connected toeach other or can be separated from each other on a layer where thefirst touch sensor metal TSM1 is disposed.

In the case that the first Y-touch routing line Y-TL-1 and the firstY-touch electrode line Y-TEL-1 are disposed to be separated from eachother on a layer where the first touch sensor metal TSM1 is disposed, aboundary between the first Y-touch routing line Y-TL-1 and the firstY-touch electrode line Y-TEL-1 can be a diagonal shape. As the repairprocess for cutting is not required even if the first Y-touch routingline Y-TL-1 and the first Y-touch electrode line Y-TEL-1 made of thefirst touch sensor metal TSM1 are shorted, a boundary between the firstY-touch routing line Y-TL-1 and the first Y-touch electrode line Y-TEL-1made of the first touch sensor metal TSM1 can be cut in the diagonaldirection in a process cutting the dummy electrode DME for a convenienceof the process.

Such as described above, the first Y-touch routing line Y-TL-1 and thefirst Y-touch electrode line Y-TEL-1 can be electrically connected toeach other as various shapes on the first sub-area SAA1.

FIGS. 14 to 17 are diagrams illustrating a specific example that a touchsensor structure of the touch display device 100 according toembodiments of the present disclosure is implemented on a peripheralarea of a boundary of the active area AA and the non-active area NA ofthe display panel 110.

FIG. 14 illustrates a peripheral area of a boundary of the active areaAA and the non-active area NA positioned adjacently to the firstsub-area SAA1 on one side (e.g., a left side) of the display panel 110according to one embodiment. FIG. 15 illustrates a peripheral area of aboundary of the active area AA and the non-active area NA positionedadjacently to the third sub-area SAA3 on other side (e.g., a right side)of the display panel 110 according to one embodiment. FIG. 16 exemplaryillustrates a specific structure which the second touch sensor metalTSM2 is disposed in an example illustrated in FIG. 14 . FIG. 17illustrates a peripheral area of a boundary of the active area AA andthe non-active area NA positioned adjacently to the second sub-area SAA2on a lower side of the display panel 110 according to one embodiment.

Referring to FIG. 14 , a first X-touch electrode contact pad X-CP-1 andthe first X-touch routing line X-TL-1 electrically connected to thefirst X-touch electrode line X-TEL-1 can be disposed on a boundary ofthe active area AA and the non-active area NA on the first sub-areaSAA1.

The first X-touch electrode line X-TEL-1 can be made of the first touchsensor metal TSM1.

Such as an example of a cross-sectional structure of C-C′ portionillustrated in FIG. 14 , the first X-touch electrode line X-TEL-1 can beextended from the active area AA to the non-active area NA, and can beelectrically connected to the first X-touch electrode contact pad X-CP-1made of the second touch sensor metal TSM2 through the contact hole CH.Alternatively, a portion made of the first touch sensor metal TSM1 whichis extended to the non-active area NA to be connected to the firstX-touch electrode contact pad X-CP-1 can be a part of the first X-touchelectrode contact pad X-CP-1.

A portion of the first X-touch electrode contact pad X-CP-1 made of thesecond touch sensor metal TSM2 can be connected to the first X-touchelectrode connecting pattern X-CL-1 disposed on the active area AA.

An example illustrated in FIG. 14 illustrates an example that the firstX-touch electrode connecting pattern X-CL-1 is constituted by threelines, but not limited to this. Any number of lines may constitute thefirst X-touch electrode connecting pattern X-CL-1.

As the first touch electrode connecting pattern X-CL-1 is made of thesecond touch sensor metal TSM2, it can be directly connected to thefirst X-touch electrode contact pad X-CP-1 positioned on the non-activearea NA and can be disposed on the active area AA. The first X-touchelectrode connecting pattern X-CL-1 can be electrically connected to theplurality of X-touch electrodes X-TE on the active area AA and canconstitute the first X-touch electrode line X-TEL-1.

Referring to FIG. 15 , a third X-touch electrode contact pad X-CP-3 anda third X-touch routing line X-TL-3 that is electrically connected to athird X-touch electrode line X-TEL-3 can be disposed on a boundary ofthe active area AA and the non-active area NA on the third sub-areaSAA3.

The third X-touch electrode contact pad X-CP-3 and the third X-touchrouting line X-TL-3 can be disposed similarly to the first X-touchelectrode contact pad X-CP-1 and the first X-touch routing line X-TL-1illustrated in FIG. 14 . The third X-touch electrode contact pad X-CP-3and the third X-touch routing line X-TL-3 can be disposed symmetricallyto the first X-touch electrode contact pad X-CP-1 and the first X-touchrouting line X-TL-1.

Such as an example of a cross-sectional structure of a D-D′ portionillustrated in FIG. 15 , the third X-touch electrode line X-TEL-3 can beextended from the active area AA to the non-active area NA, and can beelectrically connected to the third X-touch electrode contact pad X-CP-3made of the second touch sensor metal TSM2 through the contact hole CH.

Such as described above, a structure that the X-touch electrode contactpad X-CP and the X-touch routing line X-TL are disposed can be similaron both sides of the active area AA.

Whereas, a structure that the X-touch electrode line X-TEL is disposedcan be different on end portions of the both sides of the active areaAA.

For example, such as a portion indicated by 1401 in FIG. 14 , on aboundary of one side of the active area AA, the first X-touch electrodeline X-TEL-1 can be a shape (e.g., a non-opened portion) that a trianglearea corresponding to a portion opened as a rhombus shape is filled withthe first touch sensor metal TSM1.

Such as a portion indicated by 1501 in FIG. 15 , on a boundary of otherside of the active area AA, the third X-touch electrode line X-TEL-3 canbe a shape (e.g., a non-opened portion) that a triangle areacorresponding to a portion opened as a trapezoid shape is filled withthe first touch sensor metal TSM1.

That is, an opened portion in the touch electrode line TEL can bedisposed according to a certain pattern to be disposed to correspond onboth sides of the active area AA, and a shape of the non-opened portionwhich the portion opened is filled with the first touch sensor metalTSM1 can be different on both sides of the active area AA.

When the touch electrode TE disposed to contact one side boundary of theactive area AA is referred as a first boundary touch electrode and thetouch electrode TE disposed to contact another side boundary of theactive area AA is referred as a second boundary touch electrode, a shapeof an end portion of the first boundary touch electrode which contactsthe one side boundary of the active area AA can be different from ashape of an end portion of the second boundary touch electrode whichcontacts the other side boundary of the active area AA.

As the touch electrode line TEL includes an opened portion in order tocorrespond to the light-emitting area of the light-emitting element ED,a structure of the touch electrode line TEL can be different on bothsides of the active area AA according to an arrangement structure of thelight-emitting area of the light-emitting element ED.

As the light-emitting area of the light-emitting element ED is repeatedas a constant pattern, a structure of the touch electrode line TEL isdifferent on both sides of the active area AA but can be shapes relatedto each other. For example, a portion indicated by 1401 in FIG. 14 and aportion indicated by 1501 in FIG. 15 can be shapes engaged with eachother.

Furthermore, above-mentioned structure exemplary illustrates a structureof the X-touch electrode line X-TEL, but according to a structure thatthe light-emitting area of the light-emitting element ED is disposed, itcan be also applied to a case of a structure of the Y-touch electrodeline Y-TEL positioned on both sides of the active area AA. For example,in some cases, a structure of an end portion of the Y-touch electrodeline Y-TEL positioned on an upper side boundary of the active area AAcan be different from a structure of an end portion of the Y-touchelectrode line Y-TEL positioned on a lower side boundary of the activearea AA.

Furthermore, according to a structure that the light-emitting area ofthe light-emitting element ED is disposed, shapes of both end portionsof the touch electrode line TEL disposed in one direction can bedifferent from each other, and shapes of both end portions of the touchelectrode line TEL disposed in other direction can be identical orcorrespond to each other. In the case of the examples illustrated inFIG. 14 and FIG. 15 , as the light-emitting area of the light-emittingelement ED is separated by an electrode portion disposed in the firstdirection, a shape of an end portion of the Y-touch electrode line Y-TELadjacent to an upper side boundary of the active area AA can beidentical to a shape of an end portion of the Y-touch electrode lineY-TEL adjacent to a lower side boundary of the active area AA. Thus,both end portions of the X-touch electrode line X-TEL adjacent to bothsides boundaries of the active area AA can have different shapes, andboth end portions of the Y-touch electrode line Y-TEL adjacent to bothsides boundaries of the active area AA can have identical orcorresponding shapes.

Shapes of the touch electrode line TEL made of the first touch sensormetal TSM1 can be different on both sides of the active area AA such asdescribed above, but shapes of portions made of the second touch sensormetal TSM2 can be identical or similar.

FIG. 16 illustrates an example of a structure of the second touch sensormetal TSM2 disposed on an area including one sensing unit SU on one sideboundary of the active area AA.

The X-touch electrode connecting pattern X-CL for a connection of theX-touch electrode X-TE can be disposed on the active area AA. TheX-touch electrode connecting pattern X-CL can be connected to theX-touch electrode contact pad X-CP positioned outside of the active areaAA. The X-touch electrode contact pad X-CP can be connected to theX-touch routing line X-TL.

At least one Y-touch electrode connecting pattern Y-CL made of thesecond touch sensor metal TSM2 can be disposed on an area adjacent to anupper side boundary and a lower side boundary of the sensing unit SU.

The Y-touch electrode connecting pattern Y-CL can electrically connecttwo parts of the Y-touch electrode line Y-TEL separated by the Y-touchrouting line Y-TL or the first dummy electrode DME1.

Two or more Y-touch electrode connecting pattern Y-CL can be disposed onone sensing unit SU, and the Y-touch electrode connecting pattern Y-CLcan be disposed on various positions. As the Y-touch electrodeconnecting pattern Y-CL connects the Y-touch electrode Y-TE separated onan upper side and a lower side of each sensing unit SU, the Y-touchelectrode Y-TE can have a similar state to a structure not separated.

As the Y-touch electrode connecting pattern Y-CL is positioned onboundaries of an upper side and a lower side of the sensing unit SU, apoint that the X-touch electrode contact pad X-CP connected to theX-touch electrode line X-TEL is divided can be positioned betweenadjacent Y-touch electrode connecting patterns Y-CL.

For example, such as a portion indicated by 1601, a boundary between theX-touch contact pads X-CP can be identical to a boundary of the sensingunit SU.

As the Y-touch electrode connecting patterns Y-CL are disposed on bothsides of a boundary of the sensing unit SU, a boundary between theX-touch electrode contact pads X-CP can be positioned between adjacentY-touch electrode connecting patterns Y-CL.

A Y-auxiliary routing pattern Y-TLP can be disposed on an area otherthan an area where the X-touch electrode connecting pattern X-CL and theY-touch electrode connecting pattern Y-CL are disposed on a layer wherethe second touch sensor metal TSM2 is disposed.

The Y-auxiliary routing pattern Y-TLP can be disposed to be separatedfrom the X-touch electrode connecting pattern X-CL and the Y-touchelectrode connecting pattern Y-CL. The Y-auxiliary routing pattern Y-TLPcan be electrically connected to the Y-touch routing line Y-TLoverlapping the Y-auxiliary routing pattern Y-TLP and can reduce aresistance of the Y-touch routing line Y-TL disposed on the active areaAA.

The second touch sensor metal TSM2 disposed on an area overlapping thefirst dummy electrode DME1 can be disposed as a shape similar to thefirst dummy electrode DME1 and can constitute a dummy pattern DMP.

As the dummy pattern DMP is disposed on an area overlappingthe touch electrode line TEL, a visibility difference with an area wherethe touch routing line TL and the auxiliary routing pattern TLP aredisposed to overlap each other can be prevented or at least reduced.

As only the X-touch routing line X-TL driving the X-touch electrode lineX-TEL disposed on a corresponding sub-area SAA is disposed on a boundaryarea of both sides of the active area AA, an arrangement of the X-touchrouting line X-TL can be easy. The X-touch routing line X-TL can be madeof at least one of the first touch sensor metal TSM1 or the second touchsensor metal TSM2 and can be implemented as a shape reducing a lineresistance.

The second Y-touchelectrode contact pad Y-CP-2 can be disposed to cross the first Y-touchelectrode contact pad Y-CP-1 connected to the first Y-touch routing lineY-TL-1.

On an area where the second Y-touch electrode contact pad Y-CP-2 crossesthe first Y-touch electrode contact pad Y-CP-1, the second Y-touchelectrode contact pad Y-CP-2 can be disposed by using the first touchsensor metal TSM1, the first Y-touch electrode contact pad Y-CP-1 can bedisposed by using the second touch sensor metal TSM2.

Furthermore, two parts of the second Y-touch electrode line Y-TEL-2 canbe electrically connected to each other by the second Y-touch electrodecontact pad Y-CP-2 on outside of the active area AA. The second Y-touchelectrode contact pad Y-CP-2 can be disposed along an outer edge of eachof two parts of the second Y-touch electrode line Y-TEL-2. The secondY-touch electrode contact pad Y-CP-2 can be disposed such that a partmade of the first touch sensor metal TSM1 and a part made of the secondtouch sensor metal TSM2 are electrically connected to each other throughthe contact hole CH positioned on outside of the active area AA.

A structure that the first Y-touch routing line Y-TL-1 disposed on theactive area AA is extended to the non-active area NA and the secondY-touch electrode line Y-TEL-2 is connected to the second Y-touchrouting line Y-TL-2 can be provided while reducing a load increase by aseparated structure of the second Y-touch electrode line Y-TEL-2.

Aremained portion in a process of cutting an electrode for constitutingthe Y-touch electrode contact pad Y-CP and the Y-touch routing line Y-TLcan be disposed as the third dummy electrode DME3.

As the third dummy electrode DME3 is positioned between the firstY-touch electrode contact pad Y-CP-1 and the second Y-touch electrodecontact pad Y-CP-2, a short circuit defect between the first Y-touchelectrode contact pad Y-CP-1 and the second Y-touch electrode contactpad Y-CP-2 can be prevented or at least reduced.

FIG. 18 is a diagram illustrating a specific example that a touch sensorstructure of the touch display device 100 is implemented between theactive area AA of the display panel 110 and a dam DM of the non-activearea NA according to embodiments of the present disclosure.

Referring to FIG. 18 , at least one dam DM can be disposed on thenon-active area NA of the display panel 110. The at least one dam DM canbe disposed to surround the active area AA. The at least one dam DM canbe positioned on an outer portion of the encapsulation layer ENCAP. Theat least one dam DM can be a part of the encapsulation layer ENCAP.

The plurality of touch routing lines TL can be positioned inside of theat least one dam DM on the non-active area NA. The plurality of touchrouting line TL can be positioned between the active area AA and the atleast one dam DM on area other than a pad area PA.

As the plurality of touch routing lines TL are positioned inside of theat least one dam DM, the touch routing line TL can be disposed whilereducing an increase of the non-active area NA.

At least one shield line SHL can be disposed to surround at least aportion of the plurality of touch routing line TL. The shield line SHLcan be positioned between the touch routing line TL positioned outermostof the plurality of the touch routing lines TL and the dam DM.

The shield line SHL can be made of a same material to the touch routingline TL. For example, the shield line SHL can be made of at least one ofthe first touch sensor metal TSM1 or the second touch sensor metal TSM2.

The shield line SHL can be grounded. Alternatively, the shield line SHLcan receive a signal different from a signal supplied through the touchrouting line TL.

As the shield line SHL is disposed to encompass outside of the touchrouting line TL, the shield line SHL can block an external noise and canprevent or reduce that the external noise affect a signal of the touchrouting line TL.

At least one guard line GUL can be disposed between the touch routingline TL and the shield line SHL.

The guard line GUL can be made of a same material to the touch routingline TL. For example, the guard line GUL can be made of at least one ofthe first touch sensor metal TSM1 or the second touch sensor metal TSM2.

As the guard line GUL is positioned between the touch routing line TLand the shield line SHL, the guard line GUL can block that a parasiticcapacitance is formed between the touch routing line TL and the shieldline SHL. As the parasitic capacitance between the touch routing line TLand the shield line SHL is blocked, it can be blocked that a fluctuationof a signal or a voltage state of the shield line SHL affects the touchrouting line TL.

The guard line GUL can be supplied a signal corresponding to a signalapplied to the touch routing line TL positioned the most adjacent to theguard line GUL among the plurality of touch routing lines TL. The guardline GUL can be supplied a signal corresponding to a signal applied tothe touch routing line TL positioned outmost among the plurality oftouch routing lines TL.

A signal corresponding to a signal applied to the touch routing line TLcan mean a signal which is identical to at least one of a frequency, anamplitude or a phase of a signal applied to the touch routing line TL.

For example, the guard line GUL can be supplied a signal identical to asignal applied to the touch routing line TL positioned the most adjacentto the guard line GUL at an identical timing. A parasitic capacitancemay not be formed between the touch routing line TL positioned the mostadjacent to the guard line GUL and the guard line GUL. An indirect noiseby the shield line SHL can be blocked by the guard line GUL.

Such as described above, it can be blocked by the shield line SHL thatan external noise affects the touch routing line TL directly.Furthermore, it can be blocked by the guard line GUL that an indirectnoise by the shield line SHL affects the touch routing line TL. A noiseof a signal detected through the touch routing line TL can be preventedor reduced by the shield line SHL and the guard line GUL, and a signaldifference according to positions of the touch routing lines TL can beprevented or reduced.

At least one of the shield line SHL or the guard line GUL can bedisposed to be divided on the non-active area NA.

For example, the shield line SHL and the guard line GUL, such as aportion indicated by 1801, can be disposed to be divided on an extendedline of the second boundary BL2.

The touch electrode line TEL disposed on the first sub-area SAA1 and thetouch electrode line TEL disposed on the third sub-area SAA3 can bedisposed to be separated from each other and can be drivenindependently. A minute difference of driving timings of the touchrouting lines TL supplying signals to the touch electrode lines TELdisposed on each of the first sub-area SAA1 and the third sub-area SAA3can be present.

The guard line GUL being supplied a signal corresponding to a signalapplied to the touch routing line TL can be disposed to be divided to becorresponded to the sub-area SAA driven by the corresponding touchrouting line TL.

For example, as the guard line GUL positioned on sides of the firstsub-area SAA1 and the second sub-area SAA2 of the display panel 110 isthe most adjacent to the touch routing line TL driving the firstsub-area SAA1, it can be disposed to surround outside of the firstsub-area SAA1.

As the guard line GUL positioned on sides of the third sub-area SAA3 andthe fourth sub-area SAA4 of the display panel 110 is the most adjacentto the touch routing line TL driving the third sub-area SAA3, it can bedisposed to surround outside of the third sub-area SAA3.

Each guard line GUL positioned on both sides of the display panel 110can be supplied a signal corresponding to a signal applied to the touchrouting line TL at a timing that a signal is applied to adjacent touchrouting line TL.

In a structure that the touch electrode line TEL disposed on the activearea AA is divided as the sub-area SAA and driven, a noise to the touchrouting line TL driving each sub-area SAA can be blocked moreaccurately.

Examples above-mentioned are examples that the guard line GUL is dividedin a structure that the active area AA is divided as four sub-areas SAA,but the guard line GUL can be disposed to be divided variously accordingto a divided structure of the sub-area SAA.

Furthermore, the shield line SHL positioned outside of the guard lineGUL can be disposed to be divided to correspond to a divided structureof the guard line GUL.

For example, the shield line SHL can be disposed to be divided on anextended line of the second boundary BL2. Alternatively, in some cases,the shield line SHL can be disposed not to be divided.

Grounded shield line SHL can disposed to surround lines disposed on thenon-active area NA and can block an external noise. The guard line GULpositioned adjacent to the touch routing line TL can be disposed to bedivided to be corresponded to the touch routing line TL or the sub-areaSAA driven by the touch routing line TL, and can block a parasiticcapacitance between lines, and can improve an effect of a noiseblocking.
